Moving 3.4TB VM w/o vMotion

We have a 3.4TB VM (file server) that we will be moving from an ESXi 5.5 host to ESXi 6.0 host. For our smaller VM's I have used the VMWare Converter and it has worked well, although I figure it would be extremely time consuming for a 3.4TB virtual machine.

I've considered the options below. Please let me know what you think would be the best way to proceed:

1. Veeam QuickMigration.
2. Copy VMDK/VMX files from datastore on the old host to the datastore on the new host and adding it to inventory.
3. Carbonite Douletake
4. Restoring from a StorageCraft backup
5. VMWare Converter
